History Of Firefighting
The history of organized firefighting began in ancient Rome while under the rule of Augustus. Prior to that, Ctesibius, a Greek citizen of Alexandria, developed the first fire pump in the third century BC, which was later improved upon in a design by Hero of Alexandria in the first century BC. Ancient Rome The first ever Roman fire brigade was created by Marcus Licinius Crassus. He took advantage of the fact that Rome had no fire department, by creating his own brigade—500 slaves strong—which rushed to burning buildings at the first cry of alarm. Upon arriving at the scene, however, the firefighters did nothing while Crassus offered to buy the burning building from the distressed property owner, at a miserable price. If the owner agreed to sell the property, his men would put out the fire, if the owner refused, then they would simply let the structure burn to the ground.Plutarch, Parallel Lives, The Life of Crassus 2.3–4 Wallechinsky, David & Irving Wallace.Richest Peop ...

Firefighters Microcosm Edited
A firefighter is a first responder and rescuer extensively trained in firefighting, primarily to extinguish hazardous fires that threaten life, property, and the environment as well as to rescue people and in some cases or jurisdictions also animals from dangerous situations. Male firefighters are sometimes referred to as firemen (and, less commonly, a female firefighter as firewoman). The fire service, also known in some countries as the fire brigade or fire department, is one of the three main emergency services. From urban areas to aboard ships, firefighters have become ubiquitous around the world. The skills required for safe operations are regularly practised during training evaluations throughout a firefighter's career. Initial firefighting skills are normally taught through local, regional or state-approved fire academies or training courses. Depending on the requirements of a department, additional skills and certifications such as technical rescue and pre-hospital med ...

Suction And Force Pump
Suction is the colloquial term to describe the air pressure differential between areas. Removing air from a space results in a pressure differential. Suction pressure is therefore limited by external air pressure. Even a perfect vacuum cannot suck with more pressure than is available in the surrounding environment. Suctions can form on the sea, for example, when a ship founders. When the pressure in one part of a physical system is reduced relative to another, the fluid in the higher pressure region will exert a force relative to the region of lowered pressure, referred to as pressure-gradient force. Pressure reduction may be static, as in a piston and cylinder arrangement, or dynamic, as in the case of a vacuum cleaner when air flow results in a reduced pressure region. When animals breathe, the diaphragm and muscles around the rib cage cause a change of volume in the lungs. The increased volume of the chest cavity decreases the pressure inside, creating an imbalance with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manual Pump
Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities. There are many different types of hand pump available, mainly operating on a piston, diaphragm or rotary vane principle with a check valve on the entry and exit ports to the chamber operating in opposing directions. Most hand pumps are either piston pumps or plunger pumps, and are positive displacement. Hand pumps are commonly used in developing countries for both community supply and self-supply of water and can be installed on boreholes or hand-dug wells. History One sort of pump once common worldwide was a hand-powered water pump, or 'pitcher pump'. It was commonly installed over community water wells in the days before piped water supplies. In parts of Britain and Ireland, it was often called ''the parish pump' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Hautsch
Hans Hautsch (January 4, 1595January 31, 1670) was a toolmaker and inventor from Ledergasse, Nuremberg. His father, Antoni (15631627), and grandfather, Kilian (died 1570), were both toolmakers. He married Magdalena (born 1603), the daughter of carpenter Jacob Flexlein, on June 25, 1621. They had a daughter and five sons, including Georg (born 1624, also a toolmaker), Gottfried (16341703), and Johann Andreas (born 1638). Gottfried Hautsch invented the conical touch hole for muzzle-loading guns, whereby the pan closed itself, cutting loading time by two thirds. Inventions In 1649, Hans Hautsch designed a wheelchair for gout patients. Shortly thereafter, he built a self-propelled, four-wheeled mechanical cart: "It moves by itself and requires no initial preload, from a horse or anything else. The car travels 2000 paces every hour; it stops when the driver pleases, starts when the driver pleases, and works entirely on clockwork." Later, he was commissioned to produce a chariot, ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force Pump
A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without adversely affecting flow rate. Piston pumps can also deal with viscous media and media containing solid particles. This pump type functions through a piston cup, oscillation mechanism where down-strokes cause pressure differentials, filling of pump chambers, where up-stroke forces the pump fluid out for use. Piston pumps are often used in scenarios requiring high, consistent pressure and in water irrigation or delivery systems. Types The two main types of piston pump are the lift pump and the force pump. Both types may be operated either by hand or by an engine. Lift pump In a lift pump, the upstroke of the piston draws water, through a valve, into the lower part of the cylinder. On the downstroke, water passes thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Debunker
A debunker is a person or organization that exposes or discredits claims believed to be false, exaggerated, or pretentious. "to expose or excoriate (a claim, assertion, sentiment, etc.) as being pretentious, false, or exaggerated: to debunk advertising slogans." The term is often associated with skeptical investigation of controversial topics such as UFOs, claimed paranormal phenomena, cryptids, conspiracy theories, alternative medicine, religion, or exploratory or fringe areas of scientific or pseudoscientific research. According to the Merriam-Webster online dictionary, to "debunk" is defined as: "to expose the sham or falseness of." The ''New Oxford American Dictionary'' defines "debunk" as "expose the falseness or hollowness of (a myth, idea, or belief)". If debunkers are not careful, their communications may backfire – increasing an audience's long-term belief in myths. Backfire effects can occur if a message spends too much time on the negative case, if it is too co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Legend
An urban legend (sometimes contemporary legend, modern legend, urban myth, or urban tale) is a genre of folklore comprising stories or fallacious claims circulated as true, especially as having happened to a "friend of a friend" or a family member, often with horrifying, humorous, or cautionary elements. These legends can be entertaining but often concern mysterious peril or troubling events, such as disappearances and strange objects or entities. Urban legends may confirm moral standards, reflect prejudices, or be a way to make sense of societal anxieties. Urban legends in the past were most often circulated orally, but now can also be spread by any media. This includes newspapers, mobile news apps, e-mail, and most often, social media. Some urban legends have passed through the years/decades with only minor changes, in where the time period takes place. Generic urban legends are often altered to suit regional variations, but the lesson or moral remains majorly the same. Or ...

Fire Insurance Marks
Fire insurance marks are metal plaques marked with the emblem of the insurance company which were affixed to the front of insured buildings as a guide to the insurance company's fire brigade. These identification marks were used in the eighteenth and nineteenth century in the days before municipal fire services were formed. The UK marks are called 'Fire insurance plaques'. The first to use the mark was the Sun Fire Office which was established in 1710. Some period specimens remain on historical buildings in the older areas of Britain's and America's cities and larger towns. Cast metal plaques were made of iron, lead, or sometimes brass. Embossed sheet metal signs were also made, as well as flat enamel signs – the latter mostly in Continental Europe in the later 19th century. Period specimens may have high value among antiques collectors, leading to illicit creation of fakes. Also, nostalgic reproductions have been made since the early 20th century for decorative purposes. By ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
